层面 / 表现 继发孔型房间隔缺损 膜周部室间隔缺损
血流动力学
  • 肺循环与体循环血流比值：L < 1.5（无负荷过重）；M和G ≥ 1.5（伴RV容量负荷过重）[C4] [C5]。
  • 分流方向：心房水平左向右分流 [C5] [G4-04]。
  • 肺动脉压（肺动脉收缩压、肺动脉平均压）：轻度时正常；存在大量高血流时可升高 [C5]。
  • 肺循环与体循环血流比值：L较低（<1.5）；M中等；无晚期肺血管病变时G升高 [C4] [C5]。
  • 室间隔射流峰值流速及压差：L为伴大跨心室压差的高速射流；M流速中等；G因心室压力均等呈低速射流 [C5] [G4-05]。
  • 肺动脉收缩压：L正常；M正常或轻度升高；G显著升高（肺动脉高压）[C5]。
心律
  • 通常为正常窦性心律 [C5]。
  • 成年患者因慢性右心房重构和扩张可出现心房颤动或心房扑动 [C4] [C5]。
  • 通常为正常窦性心律 [C5]。
  • 由于膜周缺损与希氏束解剖位置邻近，可能发生房室传导阻滞 [E2] [G4-05]。
ECG
  • RV舒张期负荷过重引起的不完全性右束支传导阻滞（不完全性右束支传导阻滞，V1导联呈rsR'或rSr'型）[E2] [G4-04]。
  • 中度：左心房扩大（二尖瓣型P波）及容量负荷过重所致左心室肥厚（左心室肥厚电压标准）[E1] [G4-05]。
  • 重度：双心室肥厚伴V2–V4导联高大双相波群（Katz-Wachtel现象），肺动脉高压背景下右心室肥厚 [E1] [G4-05]。
心音与杂音
  • 第二心音（S2）：S2宽而固定分裂（S2固定分裂），不受呼吸影响，为房间隔缺损的特征性体征 [G1-11] [G4-04]。
  • 收缩期杂音：肺动脉瓣区因血流增多穿过正常瓣膜而闻及柔和的喷射性收缩中期杂音（2–3/6级）[G1-14] [G4-04]。
  • 三尖瓣隆隆样杂音：重度（G）时，因大血流量流经产生相对性三尖瓣狭窄，在三尖瓣区（胸骨左缘下段）可闻及柔和的舒张中期隆隆样杂音 [G1-15] [G4-04]。
  • 限制性VSD中的收缩期杂音（L/M）：胸骨左缘第 3-4 肋间（胸骨左下缘）闻及粗糙、高频、响亮的全收缩期杂音（4–6/6级）伴可触及震颤 [G1-14] [G4-05]。
  • 大型VSD中的杂音（G）：由于压力均等化呈更柔和且更短促的全收缩期杂音（2–3/6级）[G1-14] [G4-05]。
  • 第二心音（S2）：伴肺动脉高压的重度病变中肺动脉瓣成分P2亢进 [G1-11] [G4-05]。
  • 二尖瓣隆隆样杂音：在伴大量分流的重度病变中，由于跨二尖瓣血流过多在心尖部闻及功能性舒张中期隆隆样杂音 [G1-15] [G4-05]。
  • 第三心音（S3）：LV容量负荷过重时在心尖部闻及快速充盈奔马律 [G1-12]。
动脉脉搏
  • 颈动脉和外周脉搏正常 [B4]。
  • 重度LV容量负荷过重时正常或呈高动力性 [B4]。
颈静脉搏动
  • 颈静脉压正常或轻度升高，存在RV负荷过重时a波与v波明显且振幅接近 [B3]。
  • 轻度时正常；伴肺动脉高压的重度病变中出现显著a波 [B3] [G4-05]。
负荷试验
  • 呼吸：吸气与呼气之间S2分裂间期保持固定不变 [G1-11] [G4-04]。
  • Valsalva动作：用力相期间肺动脉喷射性杂音强度减弱 [B1]。
  • 等长握力试验：增加体循环后负荷并增强VSD杂音强度 [B1]。
  • Valsalva动作：用力相期间杂音减弱 [B1]。
  • 吸气：杂音强度不增加（与三尖瓣关闭不全鉴别）[B1]。
